I feel "somewhat" betrayed, although that maybe a bit too strong. What upsets me the most is that as a VIN: 5486, it was a crapshoot as to whether you got A vs. B. I can't get upset about upgrades down the line that I didn't get (parking sensors, folding mirrors, etc) since that was never promised. however, based on Elon's statements about faster charging for all Model Ss, most of us "assumed" that we would all take advantage.
I wouldn't go as far as not trusting Tesla, but I am a bit disappointed. extra time (whether it's 4 minutes or 15 minutes) at the supercharger doesn't bother me too much, but it's like buying an iPad at apple store, but I got a regular iPad while person next to me got iPad with retina display (ok, not the same, you get the gist) for the same price and at the same time.
But more importantly, person who got the B back at the same time as I did "may" have higher resale value. Which one would you rather buy, 5 years from now, everything else being equal? one with a A pack or B pack?
